[0002] In the high-temperature refractory industry, raw materials need to be screened. The traditional screening tool is a vibrating screen. The traditional vibrating screen is a screen that vibrates both the screen and the box at the same time, and the materials are screened and separated by vibration.

[0003] After searching, the Chinese patent number is CN202021117657.3, which discloses an improved high-temperature wear-resistant castable screening machine, which relates to refractory material processing equipment, including a box body, a screen is arranged in the box body, the outer edge of the screen is fixed on the inner wall of the box body, a vibrator is installed in the center of the upper surface of the screen, and the vibrator cover is provided with a sand-proof cover; a support frame is arranged at the bottom of the box body, and the support frame is composed of two support columns distributed in a triangular shape and a lifting cylinder; a magnet cover with a large upper opening and a lower lower opening is installed in the box body, and the magnet cover is installed at the bottom end of the feed inlet; a dust removal chamber is arranged on the outer top surface of the box body, an exhaust fan is installed on the top of the dust removal chamber, and a layer of filter is arranged in the dust removal chamber. The inner cavity of the dust removal chamber below the filter is connected to the top of the box body through a dust removal pipe. While screening the material, the screening machine absorbs iron impurities through the magnet cover and prevents dust from flying out of the feed inlet, thereby improving the discharge quality of the material and reducing the impact of dust on the working environment and the physical harm to the staff.

[0004] However, the above scheme still has defects. The two ends of the lifting cylinder are respectively fixed on the bottom of the box and the ground, which makes it impossible to lift the box, that is, the large-particle slag that has passed the screen cannot be gathered and discharged from the slag discharge port. In addition, the use of two exhaust fans increases the equipment cost, and when the blocked filter needs to be cleaned or replaced, the screening of the high-temperature refractory coating raw materials needs to be stopped to prevent the dust from being cleaned, which reduces the screening efficiency of the high-temperature refractory coating raw materials and brings a bad user experience.

In addition, the use of two exhaust fans increases the equipment cost, and when the blocked filter needs to be cleaned or replaced, it is necessary to stop screening the high-temperature refractory coating raw materials to prevent the inability to clean the dust, thereby reducing the screening efficiency of the high-temperature refractory coating raw materials.

When the amount of gas is less than the set minimum value, the gas flow sensor 1991 transmits a signal to the control terminal. The control terminal reminds the staff to clean or replace the filter 193. The staff opens the closed valve 195 and closes the other open valve 195, closes the open solenoid valve 199, and opens the other solenoid valve 199, so that the other filter 193 continues to filter the dust. After that, the staff can clean or replace the blocked filter 193. The high-temperature wear-resistant castable screening machine can lift the box 1994 by using the cylinder 120. In addition, the dust can be filtered by using an exhaust fan 1992, which reduces the equipment cost.
